Definitions

  • FIG. 6 is a sectional view taken along the line 6--6 of FIG. 3;
  • FIG. 11 is a perspective view similar to FIG. 4 illustrating an alternate embodiment of the invention.
  • FIGS. 1 and 2 two of the more commonly used sizes of optical fiber.
  • the optical fiber 10 has a transparent core 12 having a diameter of 125 um with a buffer coating 14 thereon which has a diameter of 250 um.
  • a strength material 16, such as Kevlar may overlie the buffer coating and an outside coating 18 can complete the package.
  • the optical fiber 20 shown in FIG. 2 has a transparent core 22 having a diameter of 125 um, a buffer coating 24 having a diameter of 900 um, and a strength member 26, and outside coating 28.
  • the pads 72 fit within the rectangular slot 62 and the oppositely disposed rib 64 and botton of gap 74 with its V groove, define therebetween the axial bore 32 for receiving the optical fiber; i.e., the buffer coating is received between 66 and 76 and the core 12 is received between 68 and 78.
  • End walls 80 are each provided with a slot 82 for receiving the core 12 and leading it into elastic means 42.
  • a first of these halves, 100 has a large internal female end 102 comprising a rectangular slot 102a having an upstanding, centrally located rib 104 therein.
  • the rib is provided with a first sector 106 and a second sector 108.
  • the second sector 108 is identical to sector 68; however, sector 106 is much wider to accommodate the larger diameter buffer coating of fiber 20.
  • the latches 56 engage respective slots 58 and pads 113 of half 101 enter rectangular slot 102a of half 100.
  • pads 112 enter rectangular slot 105.
  • Pads 112 and slot 105 thus form the receiving port for a fiber 10
  • pads 113 and slot 102a form the receiving port for fiber 20.
  • the elastic means 42 are placed in cavity 43, with an approproate index matching gel therebetween.
  • This system of splicing assemblies provides simplified manufacture and construction. No crimps are required to maintain the splice, thus, it is reuseable.
  • the optical throughput can be verified and optimized, for example, by utilizing a local injection detection system. No adhesives are required and reliable field assembly is achievable without special fixtures or tools. Further, the splice can be accomplished one fiber at a time.
